MACHINE r ortnrvrnrusnonen AND THE LIKE.

' Be it known that I, JOHN 'J. 'PFENNINGER, a citizen of. the United-States, residing at StIiouis, Missouri, have'invented a certain new Z-and" useful Machine for Dividing of which the following is such a full, clear, and exact description as skilled in the art to aivhich itl appertains to make and use the ingpdrawings, forming part of this speclficasameyieference being had to the accompanyp invention relates to machines for dividiiig' dough andthe'likc intosmall pieces" 'ofiuni-forr'n "silos; and "is intended primarily for :usswin dividing a sheet of dough into piecesadapted to be used in pretzel making machines; It may, however, be used for an .,purpose where itis' desirable to d1v1de doug xterm i-sizeitr' I similar material are expanded laterally by the divides them transversely, so that the sev- .zere'd pieces are liable .to be forced into contact so as tostick together. 1 'tionis that the or similar material into small pieces of uni- Machin f for ividing a sheet of dough or have been previously made iniwhich the sheet of material was first divided I longitudinally" into strips and the vstripsi then transversely divided while lying side. by side. Theobjection to machines of this construction is that the strips of dough knife which Another objecpieces' are so close together that 'ev'eni-f they donot adhere, it is very difiicultto have them fall properly upon the gang convcyerswhich convey them to the .m'achineswhich are to operate upon them.

- I ;.'In practising my invention, I carry alter- .Iiate strips of'the material, after the sheet has been diyided into strips, to different secondar "conveyers where they are trans. versely divided. In this way I overcome the difliculties above referred to. I

In the ac'companying drawings, which illustrate one form of the machine made in .accordance with my invention, Figure 1 is a vertical longitudinal section; Fig

v 2 is a top plan View; Fig. 3 is a side elevation, and Fig. 4 is a central cross section. Similar numerals of reference refer to the ings'.

10 and 11 are the side frames of the masame parts in the several views of the drawchine, These frames 10 and 1 1 are con- Specification of Letters Patent. Y mass an October i911.

nected by cross-bars Journaled in the frames 10 and. 11: is a main roll 13, which is surrounded .by an endless belt 14 forming the main conveyer of the machine. This belt 14 also passes around a second roll 15. Extending between rolls 13 and 15 so as to support the upper strand ofthe belt "14:, is a table 16 supported by cross-pieces l7 resting on the frames 10 and 11. The sheet of dough 1 8 is placed upon the belt 14 directly above the table 16. Arranged above the table 16'and adjacent the roll 13 is a roll 19' and a roll 26. Cooperating with the roll 23 and roll 25, respectively, are a pair of cut ting blades .28. These blades 28 are suspended by means of rods 29 from rock shafts 30 and are actuated by means of cams 31 on shafts 32. The blades are held against the cams 31 by means of coil springs 33, as

best shown in Fig. 1. Arranged below the driving roll 23 is a gang of .conveyers 35 and below the roll 25 a similar gang of conveyers 36. These conveyors 35 and 36 are adapted to convey the pieces of dough severed from the strips by means of the blades 28. In order to convey the trimmedwfi edges of the sheet of dough laterally from the machine, I provide between the rolls 2% and 26 a trough 37 below which is a conveyer 38 which is mounted upon rolls 39 and 40, respectively.

In order to drive the machine I provide the driving shaft of the gang of conveyers 36 with a pulley 12 as shown in Fig. 2, around which the driving belt is passed. At the opposite end of the shaft is provided; a sprocket wheel 43, around which passes sprocket chain 44 also surrounds a wheel L45, 'upon This shaft 32 is.

sprocket the adjacent shaft 32. (provided with a second .sprocket wheel .46 around which passes a sprocket chain 4 This" v with a pawl 53. with wheels 5a which are mounted upon the sprocket chain 47, which, in turn, passes around a sprocket l8 upon a short shaft 49 provided with a crank 50. This crank 50 is provided with three pitmen rods 51 which are each connected'to an arm 52 provided These pawls 53 engage shafts of the rolls 13, 23 and 25, respectively, so that as the shaft 49 is rotated, intermittent movement will be imparted to said rolls. The shaft 49 also has mdunted upon it a sprocket wheel 56 around which passes a sprocket chain 57 whichalso passes around a sprocket wheel 58 upon the shaft 32 at the opposite end of the machine from the shaft 32 above referred to. This shaft 32 also has mounted upon it a sprocket wheel 59 around which passes a sprocket chain 60. This sprocket chain 60 also passes around a sprocket wheel 61 upon the shaft of the gang conveyer' 35. Theopposite end of this shaft is provided with a bevel gear wheel 62 meshing with the bevel gear wheel 63 upon a shaft 64 which carries the roll 40 driving the belt 38.

The operation of my machine will be obvious from the above description.

The sheet of dough 18 is placed upon the belt 14 above the table 16 and by the movement of said belt is carried under the roller 19 where it is rolled to a uniform thickness and then passes under the rotary cutters 20 which cut the dough into strips of uniform width. The trimmed edges of the dough pass directly from the roll 13 on to the transverse conveyer 38 where they are delivered laterally fromthe machine. The strips of dough into which the sheet is divided are led to the conveyers 21 and 22, respectively, alternate strips being led to each conveyor. The strips, as they pass around the rolls 23 and 25, respectively, are divided at uniform intervals into small pieces by means of the knives 28, and said strips are so far apart when this division occurs that they cannot possibly be spread into contact with each other, and, furthermore, the strips are small in comparison with the individual conveyers of the gangs of conveyers 35 and 36, and consequently they cannot the proper conveyer.

It will. be evident that by the gearing above described a continuous movement is imparted to theconveyers 35 and 36 and the shafts 32 which actuate the cutters while intermittent movement is communicated to the rolls 13, 23 and 25,

so that the strips of dough are at rest while they are being operated upon by the cutters 28.

I claim:
